Hi, I haven't been able to figure out how to use HMD mode correctly. I'd like to use a sensor that is attached to the head. I don't like the way the virtual input device provided in the example directory is connected to the head using the sensor update class. Reading the manual there is a function that should allow me to attach to the HMD: Viewer viewer = universe.getViewer(); viewer.getView().setTrackingEnable(true); viewer.getView().setMonoscopicViewPolicy(View.LEFT_EYE_VIEW); viewer.getView().setViewPolicy(View.HMD_VIEW); viewer.getPhysicalEnvironment().addInputDevice(tracker); viewer.getPhysicalEnvironment().setSensor(0, sensor); viewer.getPhysicalEnvironment().setHeadIndex(0); This however does not seem to work. Any ideas how to use the HMD, any example code I can borrow?
